Hi all,
I have linux 2.4.25 on a mips processor. Other than my application, the
other processes that are running on the system are udhcpd, dhcpd,
mini_dns etc. The applicaiton is quite memory intensive, it has
allocated 5 MB of a buffer which acts as a queue and the applicaiton
queues and de-queues packets in the queue at frequents intervals. The
memory for this buffer is allocated just once when the application
starts at the time of boot. So I would assume that there would be quite
a lot of paging going on.
The issue is that randomly the application gets killed, there is no
segmnetation fault or anything and if I look at /var/log/messages I see
quite a lot of
__alloc_pages: 0-order allocation failed __alloc_pages: 0-order allocation failed __alloc_pages: 0-order allocation failed
and then
VM: killing process
